We know that many animals do not stay in one place. Birds,fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily,but others move to get away from places that are too crowded.
When cold weather comes,many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration（迁移）is probably the migration of the fish which is called “salmon”.This fish is born in fresh water but it travels many miles to salt water.There it spends its life. When it is old,it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they bccome too crowded. They move down to the low land. Sometimes they move all the way the seadide,and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of kind of lobster（龙虾）.Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody know where they go.
So,sometimes we know why humans and animals move from one place to another,but at other times we don’t. Maybe living things just like to travel..Most animals move from one place to another at a certain time to _____

| How do astronauts have meals? Eating in space is different from eating on the earth. The food that astronauts carry with them doesn’t look like the food you eat on the earth. Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the space capsule(太空舱), the astronaut puts the water back. He “shoots” hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag. Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at a time. There can be no crumb(食物碎屑) floating around the capsule. Meat, cakes and cereal often come in bite-sized pieces. Astronauts can’t drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth. Eating in space is not easy. Astronauts must learn to eat this way. |

Enjoying a better life at school, with shorter class hours, greater privacy(隐私)and more rights is all you dream of, right?
For students in Shanghai, they are no longer just dreams. This week experts(行家)and law-makers in Shanghai had a meeting to talk about a new law(法律). It is called the “Shanghai Underage Protection Law(上海未成年人保护法)”.
The law says students’ diaries and letters are their secrets and “Nobody can read them if they don’t agree.”
Do your teachers sometimes say something bad to you? Maybe they send you out of the classroom because you fail to finish doing your homework. If this happens in Shanghai, you can stand up and say “No”.
Shanghai students may have less homework because of the law. Class hours may become shorter for juniors next year, down from 45 minutes to 40 minutes in some schools.
The law also talks about students’ health. According to the rules,“Smoking in these places full of kids is not allowed.”That means you can ask your teacher to stop if he smokes in a classroom.
The law makes schools safer for students. “No dancing halls, Internet bars or computer game bars are allowed within(在……以内)200 meters of a school gate.” the law says.
The law is great, right? Many students like it.
“My mom reads my diaries sometimes. I think she will be afraid if I tell her she is doing something against the law.” said Luo Jia, 13, at Shanghai Fuxing Junior School.
